Abstract

Process for producing a barrel from thermoplastic material by blowmoulding in a blowmould which is split in two and can be closed by a butt joint. The barrel has a barrel body, barrel ends and rolling hoops moulded on in the transitional region between barrel body and barrel ends. In at least one barrel end, it has two bung holes at the rim in the region of the butt joint of the blow mould. One of these bung holes is designed as a complete-emptying bung hole. For this purpose, in the blow-moulding operation, following on from the barrel body there is moulded on a cylindrical eversion in the barrel end. The head of the eversion is removed after demoulding and adequate cooling of the barrel. A bung hole collar is left and a preformed bung hole nipple with a socket piece is welded onto the bung hole collar. <IMAGE>

Description

Das Hauptpatent geht aus von einem Verfahren zur Herstellung eines Fasses aus thermoplastischem Kunststoff, wobei in eine längs einer Stoßnaht zweigeteilte, geschlossene Blasform ein thermoplastifizierter Schlauch aus einem geeigneten Kunststoff eingeführt und der Schlauch in der Blasform zu einem ein­ teiligen Faß aus Faßmantel, Faßböden sowie im Übergangsbereich zwischen Faßmantel und Faßböden angeformten Rollreifen aufge­ blasen wird und wobei in zumindest einem Faßboden Spundlöcher ausgebildet werden, von denen eines außerhalb des Bereiches der Stoßnaht der Blasform ein Vollentleerungs-Spundloch ist. Dem Hauptpatent liegt die Aufgabe zugrunde, dieses Verfahren so zu führen, daß die Gestaltfestigkeit des hergestellten Fasses im Bereich des Vollentleerungs-Spundloches verbessert wird. Dazu lehrt das Hauptpatent, daß zur Bildung des Vollentleerungs- Spundloches bei dem Blasvorgang im Anschluß an den Faßmantel eine zylindrische Ausstülpung im Faßboden durch Blasen ausge­ formt wird, daß der Kopf der Ausstülpung nach Entformen und ausreichendem Erkalten des Fasses entfernt wird, wobei ein Spundlochkragen stehengelassen wird, und daß auf den Spundloch­ kragen ein vorgeformter Spundlochnippel mit einem Muffenteil­ stück aufgeschweißt wird. - Ein Vollentleerungs-Spundloch schließt in einem Faßboden so dicht und praktisch stufenfrei an den Faßmantel an, daß durch Kippen des Fasses eine vollstän­ dige Entleerung möglich ist.The main patent is based on a manufacturing process a barrel made of thermoplastic material, being in a Closed blow mold split in two along a butt seam thermoplastic hose made of a suitable plastic inserted and the hose in the blow mold into one partial barrel made of barrel jacket, barrel bottoms and in the transition area Roll-on tires formed between the barrel jacket and the barrel bottoms will blow and in at least one barrel bottom bung holes be trained, one of which is outside the area of Butt joint of the blow mold is a fully emptied bunghole. The The main patent is based on the task of this method lead that the structural strength of the barrel produced in Area of the full drain bung hole is improved. To the main patent teaches that for the formation of the Bung hole in the blowing process following the barrel jacket a cylindrical protuberance in the bottom of the barrel by blowing is formed that the head of the protuberance after demolding and sufficient cooling of the barrel is removed, with a Bunghole collar is left, and that on the bunghole collar is a preformed bunghole nipple with a sleeve part piece is welded on. - A fully emptied bunghole closes so tightly and practically step-free in a barrel bottom to the barrel jacket that a complete by tilting the barrel final emptying is possible.

In der Praxis werden auch Fässer aus thermoplastischem Kunst­ stoff verlangt, die grundsätzlich den eingangs beschriebenen Aufbau aufweisen, bei denen jedoch insgesamt nur zwei Spund­ löcher und diese im Bereich der Stoßnaht der Blasform angeord­ net sind.In practice, barrels are made of thermoplastic art substance that basically described the above Have structure, but only a total of two bung holes and these in the area of the butt of the blow mold are not.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, bei der Herstellung von Fässern mit zwei Spundlöchern eines dieser Spundlöcher als Vollentleerungs-Spundloch auszubilden und auch dabei die Gestaltfestigkeit im Bereich dieses Vollentleerungs- Spundloches zu verbessern.The present invention is based on the object Production of barrels with two bung holes one of these Form bung holes as fully emptied bung holes and also the dimensional stability in the area of this full emptying Improve bunghole.

Gegenstand der Erfindung ist zur Lösung dieser Aufgabe ein Ver­ fahren zur Herstellung eines Fasses aus thermoplastischem Kunststoff durch Blasformen in einer zweigeteilten, mit einer Stoßnaht schließbaren Blasform, welches Faß einen Faßmantel, Faßböden sowie im Übergangsbereich zwischen Faßmantel und Faß­ böden angeformte Rollreifen aufweist und welches Faß in zumin­ dest einem Faßboden im Bereich der Stoßnaht der Blasform rand­ seitig zwei Spundlöcher besitzt, wobei eines dieser Spundlöcher als Vollentleerungs-Spundloch ausgebildet wird und dazu bei dem Blasvorgang im Anschluß an den Faßmantel eine zylindrische Aus­ stülpung im Faßboden ausgeformt wird, wobei der Kopf der Aus­ stülpung nach Entformen und ausreichendem Erkalten des Fasses entfernt sowie ein Spundlochkragen stehengelassen wird und wo­ bei auf den Spundlochkragen ein vorgeformter Spundlochnippel mit einem Muffenteilstück aufgeschweißt wird.The invention provides a solution to this problem drive to manufacture a barrel from thermoplastic Plastic by blow molding in two parts, with one Butt weldable blow mold, which barrel a barrel jacket, Barrel bottoms and in the transition area between barrel jacket and barrel Bottom molded roll tires and which barrel in at least a barrel bottom in the area of the butt joint of the blow mold edge has two bung holes on the side, one of these bung holes is designed as a fully emptied bunghole and for this purpose Blowing process following the barrel jacket a cylindrical off upturn is formed in the barrel bottom, with the head off inversion after demolding and sufficient cooling of the barrel removed and a bunghole collar is left where and where with a preformed bunghole nipple on the bunghole collar is welded on with a socket section.

Die Erfindung beruht auf der Erkenntnis, daß das Verfahren nach dem Hauptpatent auch bei der Herstellung von Fässern mit ledig­ lich zwei Spundlöchern vorteilhaft angewendet werden kann. Man erreicht sogar eine besonders weitgehende Verbesserung der Ge­ staltfestigkeit im Bereich des Vollentleerungs-Spundloches, weil die Ausstülpung im Bereich der Stoßnaht der zweigeteilten Blasform vorgeformt werden muß und in diesem Bereich der auf­ zublasende Schlauch nach Maßgabe der Ausstülpungskontur abge­ quetscht wird, was dazu führt, daß bei der Ausformung die Blas­ verformung nur klein ist und der Spundlochkragen eine verhält­ nismäßig große, durch die Blasverformung nur wenig geschwächte Wanddicke aufweist, was zur Gestaltfestigkeit einen positiven Beitrag leistet. Die Gestaltfestigkeit wird durch den auf den Spundlochkragen aufgeschweißten Spundlochnippel weiter ver­ größert.The invention is based on the knowledge that the method according to the main patent also for the production of single barrels Lich two bung holes can be used advantageously. Man even achieved a particularly extensive improvement in Ge Stability in the area of the fully emptied bunghole, because the protuberance in the area of the butt joint of the two-part Blow mold must be preformed and in this area the blowing hose according to the protuberance contour  is squeezed, which leads to the blow during molding deformation is only small and the bunghole collar behaves one large in size, only slightly weakened by the blow molding Has wall thickness, which is a positive for the structural strength Contributes. The dimensional stability is determined by the Verge bunghole collar welded bunghole nipple enlarged.

Im folgenden wird die Erfindung anhand einer lediglich ein Aus­ führungsbeispiel darstellenden Zeichnung ausführlicher er­ läutert. Es zeigen in schematischer DarstellungIn the following the invention is based on only one off leadership illustrative drawing in more detail he purifies. They show a schematic representation

Fig. 1 eine Draufsicht auf ein Faß aus thermoplastischem Kunst­ stoff, welches nach dem erfindungsgemäßen Verfahren her­ gestellt worden ist, Fig. 1 is a plan view of material in a barrel of thermoplastic synthetic which is provided by the novel process here,

Fig. 2 einen Schnitt in Richtung A-A durch den Gegenstand nach Fig. 1 im oberen Teil des Fasses, Fig. 2 is a section in direction A by the subject matter according to Fig. 1 in the upper part of the barrel,

Fig. 3 den vergrößerten Ausschnitt B aus dem Gegenstand nach Fig. 2 und Fig. 3 shows the enlarged section B from the object of FIG. 2 and

Fig. 4 und 5 einzelne Verfahrensstufen bei dem erfindungsge­ mäßen Verfahren. FIGS. 4 and 5 individual process stages in the erfindungsge MAESSEN method.

Aus einer vergleichenden Betrachtung der Fig. 1 und 2 entnimmt man, daß es sich bei dem hergestellten Faß 1 um ein in der grundsätzlichen Gestaltung einteiliges Faß handelt, welches einen Faßmantel 2, Faßböden 3 sowie im Übergangsbereich zwischen Faßmantel 2 und Faßböden 3 angeformte Rollreifen 4 aufweist und welches in zumindest einem Faßboden, im Ausfüh­ rungsbeispiel im oberen Faßboden 3, im Bereich der Stoßnaht der Blasform randseitig zwei Spundlöcher 5, 6 besitzt. Das rechte dieser Spundlöcher 5, 6 ist als Vollentleerungs-Spundloch 6 ausgebildet. Das Faß wurde durch Blasformen in einer nicht dar­ gestellten zweiteiligen, mit einer Stoßnaht schließbaren Blas­ form hergestellt.From a comparative view of FIGS. 1 and 2 it can be seen that the barrel 1 produced is a barrel in one piece in its basic design, which barrel barrel 2 , barrel bottoms 3 and in the transition area between barrel jacket 2 and barrel bottoms 3 molded roller tires 4 has and which has at least one barrel bottom, in the example Ausfüh in the upper barrel bottom 3 , in the region of the butt joint of the blow mold two sheet holes 5 , 6 . The right of these bung holes 5 , 6 is designed as a fully emptied bung hole 6 . The barrel was made by blow molding in a two-part, not shown, with a butt weldable blow mold.

Aus einer vergleichenden Betrachtung der Fig. 3 bis 5 entnimmt man, daß bei dem Blasvorgang im Anschluß an den Faßmantel 2 eine zylindrische Ausstülpung 7 im Faßboden 3 angeformt wurde (vgl. Fig. 4). Der Kopf der Ausstülpung 7 wurde nach Entformen und ausreichendem Erkalten des Fasses entfernt, wie sich aus der Fig. 5 ergibt. Der Spundlochkragen 8 blieb stehen. Be­ trachtet man die Fig. 3, die einen Ausschnitt aus dem fertigen Faß darstellt, so erkennt man, daß auf den Spundlochkragen 8 ein vorgeformter Spundlochnippel 9 mit einem Muffenstück 10 aufgeschweißt wurde. Auf diese Weise erhält man im Bereich des Vollentleerungs-Spundloches 6 statische und festigkeitsmäßige Verhältnisse, die die Gestaltfestigkeit des Fasses 1 im Bereich des Vollentleerungs-Spundloches 6 vorteilhaft verbessern.From a comparative examination of FIGS. 3 to 5 it can be seen that a cylindrical protuberance 7 was formed in the barrel base 3 during the blowing process following the barrel jacket 2 (cf. FIG. 4). The head of the protuberance 7 was removed after demolding and sufficient cooling of the barrel, as can be seen in FIG. 5. The bunghole collar 8 stopped. Be looking at Fig. 3, which shows a section of the finished barrel, you can see that a preformed bunghole nipple 9 has been welded to the bunghole collar 8 with a socket piece 10 . In this way, static and strength conditions are obtained in the area of the fully emptied bunghole 6 , which advantageously improve the structural strength of the barrel 1 in the area of the fully emptied bunghole 6 .
